Injection Molding with Epoxy Material

Hello Everyone,

We are using injection molding machine with epoxy material,may i know the distance between the nozzle end cap and screw tip.Is there any spec for this?

The issue, we are getting shot fill in the same area.

1.We have checked the tool,ther is no dent anything

CT Selection for Differential Protection

I have a transformer rated 11000/440V,50 Hz,1500kVA. the primary current is 100A and secondary current is 2000A. If is want to use differential protection, then i need to consider class PX CT on both primary and secondary sides. the problem is. the primary voltage is 11000V and secondary voltage is

Texas Instruments

I just tried for the first time ever, obtaining free samples from about 10+ semiconductor manufacturers. Texas Instruments has by far in my limited one day experience, come out on top. I bagged about 5 items at 25 items a lot. Their support is perceived to be miles ahead (as is their software) from

Paralleling of CTs

Hi,

I would like to ask some questions on paralleling of transformers:

1) what are the points that we need to consider on paralleling of CTs?

2) does the two feeders with the CTs in parallel (for example) need to be energized at all time?

Duty of pump

I have one query related to the duty of pump. The type of pump is VT. While giving the specifications, the vendor for pump has mentioned the duty of pump as on and off. What does that term refer to.

Thanks

Synthetic Biology Cells Produce Light Show

From: BBC News Website

Scientists have produced a very unusual light show, engineering bacterial cells to fluoresce in synchrony.

The researchers turned the cells into synchronised "genetic clocks" - programming them to switch a fluorescent protein on and off.

Engineers 'Can Learn From Slime'

From: BBC News Website:

The way fungus-like slime moulds grow could help engineers design wireless communication networks.

Scientists drew this conclusion after observing a slime mould as it grew into a network that was almost identical to the Tokyo rail system.

Bootable CD or USB

Is there any "easy" way to make an XP bootable cd that will allow me to remove a corupted file that is preventing my computer from booting. It is not part of the OS and was corrupted in an "Automatic update" from windows. I do have the original XP disk but it tries to reload the OS. I also have re

Running a Piston Compressor with a VSD

Good day engineers.

I have a piston compressor that I want to install and use a VSD for controls. A certain Engineer told me that one can not use a VSD on a piston compressor. Is this true? What are the disadvantages of using a VSD on the piston compressor.

Why Two Filters for Upstream of Servo Valve?

Hello,

In a hydraulic circuit of a particular hydraulic system, I noticed that there were two parallel pressure line filters without by-pass valve provided to the upstream of the servo valve, both the filters were of same rating viz. 3 micron, and shut off valve of both filters were in open

Measuring Filter Capacitors

I am trying to check whether the 2 pieces of EPCOS 1-line filter feed-through capacitors are still in good condition. Description: EPCOS 1-line filter capacitor. Part Number: B85121-A-B6 Value: 0.05 mfd (Y) 25A, 250V AC 60 Hz, 440V DC Type: Feed-Through Usage: The two filter capacitors wer
